What happens to an electron's wave packet if an accurate velocity measurement is performed?
A) It suddenly changes to a new wave packet having a very small uncertainty in position, but a large uncertainty in velocity.
B) Neither the wave packet nor the electron is affected by the measurement.
C) It suddenly changes to a new wave packet having a very small uncertainty in velocity, but a large uncertainty in position.
D) The wave packet is unaffected by the measurement, even though the electron itself makes a sudden change of state that is caused by the measurement.
E) It suddenly changes to a new wave packet having small uncertainties in both velocity and position.

According to the Heisenberg Uncertainty Principle, accurately measuring an electron's velocity increases the uncertainty in its position, resulting in a wave packet with a small uncertainty in velocity but a large uncertainty in position.
